heating and water supply

Vigorous all day! I ask for your help, misters forumites.
If already discussed, direct where... I wish to construct a tear for northwest latitudes of Russia.
Question:as is pumped water and than warmed up where there is a gas cylinder? To what to install the unit for heating in "bedroom" in subzero temperatures?
I wait for council!
Yours faithfully, RUSSIA!
